"Tags: Crossover, Invincible, Combat, Technical" "Synopsis: --This book is for singles---" "Shiki, can you act cute?" "Are you an idiot? Asking such a question?" "Not cute? How about some fan service?" "I'll kill you, really." "Sigh! With you like this, it's difficult for me too. How am I supposed to recruit readers? To save the author from starvation, debut as a Heroic Spirit, Shiki!" "Hmph, you might as well starve to death. I think that's better." "Don't you know? Ryougi Shiki, the only thing she can do." "That is," [As long as it's alive, even if it's a god, I'll kill it for you to see.] Simple and powerless, please read. The story will get better and better.
